To all whom it may concern:

Be it known that I, HENRY N. bessern, a citizen of the United States,residing at Manchester, in the county of Hillsborough e and State of NewHampshire, have invented certain new and useful Improvements in ThreadGuides, of which the following is a specification, reference being hadto the accompanying drawings;

l ments in thread guides and has relation more particularly to a deviceof this general character especially designed and adapted -for use inspooling and it is an object of the ini vention to provide a device ofthis general characterhaving novel and improved means- -whereby scrapingof the yarn is prevented as the same travels through the guide.

Another object of the invention is to pro` vide a novel and improveddevice of this general character comprising an adjuster wheel to eiectthe proper setting of -the thread on the s cols.

It is also an o ject of the invention to provide a novel and improvedguide of this general character which operates to prevent the making ofbad spools and which com rises in its'construction a tension post whicoperates, as the spool grows larger, to increase the tension on thethread and thus make a harder and better spool.

The invention consists in the details of construction and in tli'ecombination and arrangement of the several parts of my improved s threadguidev whereby certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set 40 forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to theaccompanying drawings,wherein l Fi re 1 is a fragmentary view somewhat of a iagrammaticcharacter partly in elevation and artly in section illustrating a threadguidb constructed in accordance with an embodiment of my invention;

partly iii top plan of the guide as illustrated in Figure 1;

yFigure 3 is 'a view in front elevation of my improved guide as hereinset orth;

VFigure 4 is a sectional view taken substantially on the line 4-4 ofFigure 2;

As disclosed in the accom any/ing drawings, B denotes an arm or rodsuitably supported by the spooler and with which is clamped or otherwisesecured a tensioning device.

The tensioning device as herein disclosed comprises two sections X andY. The section X comprises a base block 1 provided at its forwardmarginal portion with an upstanding blade 2, the block 1 having itslower portion. extending beyond the inner edge of tlieblade. The sectionY includes a base 3 having an upper extension 4 overlying the extendedportion 5 of the base 1 of the section X and the forward portion of thebase-3 and the extension 4 thereof is provided with an upstanding vblade6 substantiall in duplicate of the blade 2. The opposedl edges of theblades 2 and 6 have their lower portions in parallelism 'with theirupper portions disposed on predetermined outward curvatures.

The sections X and Y are adapted to be adjusted one with respect to ltheother in accordance with the count or number of yarn desiredl and asherein disclosed this adjustment is elected through the instrumentalityofv the bolt 7 disposed loosely through the outer end of the base 3 ofthe section Y and in threaded engagement withV the opposed end portionlof the extension 5 of the base 1 of the section X, as is particularlyillustrated in Figure 4. The head 7a of the bolt 7 has direct contactwith the outer end of the base 3 so that when the bolt 7 is turned inone direction the section Y will be moved toward the section X. Theopposed faces of the base 3 and the exten- `sion-5 are. provided withthe registerin or aligned sockets' 8 in which is mounte an expansiblemember 10 herein disclosed as a coiled s ring encircling the bolt 7.When the bolt the sprin or expansible member 10 serves to move nesection Y in a direction away from the section X.

is rotated in the reversed direction,

. extension 5 of the base 1.

The thread from the bobbin Z or the like is dropped by the spool tenderbetween the jaws afforded by the blades 2 and 6 and thence to the spoolS it` being understood that the sections X and Y having been irstrelatively adjusted in accordance with the count or number of the threador yarn.

In lorder to assure the maintenance of the sections X and Y in desiredadjusted relation I find it of advantage to employ the holding screw 11threaded through the base 3 and having clamping contact with the bolt 7.

Extending upwardly from the base 3 inwardly of but in close proximitytothe blade 6 is a tension post 12 which serves to prevent the threadfrom scraping on the right blade 6 and as the spool grows bigger, thepost 12 will give an'added tension to the thread resulting in a harderand betten s ool.

pExtending outwardly from the base 1 adjacent the outer end thereof isan arm 15 and extending inwardly from the arm 15 and carried thereby isa stub shaft 16,1 said shaft having its outer or free end terminating inclose proximity to the free end of the Eccentrically mounted upon thest-ub shaft 16 is an` adjustable wheel 17 the pe-i riphery of whichbeing grooved to receive a thread.

Threaded upon the stub shaft 16 at opposite sides of the wheel17 are theclamping nuts 18 which serve to hold the adjuster wheel in its differentpositions about the shaft 16. By proper rotation of the wheel 17, aproper setting will be eiected of the thread with respect to the spools,the wheel being adjustable to vary the path of the f thread through theguide to minimize wear.

From the foregoing description it is thought to be obvious that a threadguide constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that mylinvention issusceptible of some change and modification withoutdeparting from the principles and spirit thereof1 and for this reason Ido not .wish to be understood as limiting myself to sections beingLacona? aligned with the inner edge of one of the blades.

2. A guide of the class described comprisaligned with the inner edge ofsaid blade.

3. A guide of the class described comprising two sections, means foradjusting the same one with respect to the other, said sections beingprovided with upstanding blades providing jaws between which a thread isadapted tobe disposed, an upstanding guiding ost carried by one of thesections, and vertlcally adjustable means carried by one of the sectionsfor setting the thread, said vertically adjustable means and a side ofthe post being substantially aligned with the jaw between the blades.

4. A guide of the class described comprising two sections, means foradjusting the same one with respect Ito the other, said provided vwithupstanding blades provi ng jaws between which a thread lis adapted to bedisposed, an upstanding guiding post carried by one of the sections, andan eccentrically mounted wheel carried by one of the sections, saidwheel and a side of the post being substantially aligned with the jawbetween the blades.

5. A guide of the class described comprising two sections, means foradjusting the same one with respect to the other, 'said sections beingprovided, with upstanding blades providing jaws between which a threadis adapted to be disposed, an u standing guiding post carried by one oftliie sections, and an eccentrically mounted wheel carried by one of thesections, in advance of the blade carried thereby, said wheel and a sideof the post being substantially aligned with the jaw between the blades.

6. A guide of the! class described comprising two sections, means foradjusting the same one with respect to the other, said sections beingprovided with upstanding blades providing jaws between which a thread isadapted to be disposed, an upstanding guiding post carried by one of thesections, an outstanding arm carried by one of the sections, a stubshaft carried by said arm, an adjuster wheel eccentrically mounted onsaid stub shaft, and means for holding said wheel a ainst movement aboutthe stub shaft, said w eel and a side of the post being substantiallyaligned with the jaw between' the blades.

7*. A guide of the class described comprising a member provided with aslot through which a thread is adapted to be disposed, an

upstandng guide post carried bythe member and having a side thereosubstantially aligned with an edge of the slot, and means carried bysaid member to vary the path of the thread through the slot.

8. A guideof the class described comprising a member provided with aslot through which pa thread is adapted to be 'disposed` an upstandingguide post^`carried by the member andhaving a keide thereof substan- 15tially aligned YWith an edge of the slot, end y means carried by saidmember to vary 'the path of the thread through the slot, said post beingrearwardly of the slot.
